Here is a list of the top 10 most fuel-efficient cars in the Indian market, and surprisingly, the list has only one Maruti Suzuki car
With the introduction of more stringent BS6 emission norms, a lot of manufacturers ended up parting their way from diesel powertrains in the Indian market, since upgrading diesel engines to comply with the new regulations was a pretty costly affair, and would end up increasing the car’s price by quite a margin.
Hence, the list of most fuel-efficient cars that was earlier dominated by Maruti Suzuki, now looks way more different. As of now, the Hyundai Aura is the most fuel-efficient car in the Indian market, with its 1.2L diesel engine (75 PS/190 Nm) returning a fuel efficiency of 25.4 kmpl.
The second place is taken up by Tata Altroz 1.5L Diesel (90 PS/200 Nm), which delivers 25.11 kmpl. The third and fourth spots are also secured by Hyundai cars, i.e. Grand i10 Nios and Verna respectively. The Grand i10 Nios 1.2L (75 PS/90 Nm) Diesel has a fuel efficiency rating of 25.1 kmpl, while the Verna 1.5L Diesel (115 PS/250 Nm) returns 25 km to the litre.
